The technical problem that the existing overhead ground wire is lack of a bird repelling device is solved. An overhead ground wire bird-preventing device comprises a pair of fixing frames for connecting with an overhead ground wire; a main shaft is rotatably supported between the fixed frames; a turning plate is fixed on the main shaft; the main shaft penetrates through the turning plate and does not penetrate through the long central line of the turning plate. The utility model provides an overhead earth wire do not have the current situation of anti-bird device, be a small, be convenient for installation, prevent that the bird is effectual overhead earth wire anti-bird device. And is different from the traditional barbed bird-preventing device, is harmless to birds and cannot injure the birds.

Description

Overhead ground wire anti-bird device

Technical Field

The utility model relates to a transmission line takes precautions against bird pest trouble prevent bird device is a prevent bird device of taking precautions against large-scale birds and perching in overhead earth wire top.

Background

At present, the overhead ground wire of the power transmission line is not provided with a bird prevention device or a bird damage area, when large birds (such as geranium wilfordii) reach a certain number, individual birds can stand above the overhead ground wire to perch, and when the large birds (such as geranium wilfordii) perch above the overhead ground wire to discharge excrement, the excrement can cause short circuit and brake drop of the overhead ground wire and a wire.

Therefore, it is very desirable to develop a bird prevention device for an overhead ground wire of a power transmission line, which can be installed above the overhead ground wire connected with a truss structure to prevent large birds from standing on the overhead ground wire, effectively solve the current situation that the overhead ground wire has no bird prevention device, and improve the healthy operation level of the power transmission line.

Disclosure of Invention

The utility model discloses a solve present overhead earth wire and lack a bird repellent device's technical problem, provide an overhead earth wire anti-bird device.

The utility model discloses an adopt following technical scheme to realize: an overhead ground wire bird-preventing device comprises a pair of fixing frames for connecting with an overhead ground wire; a main shaft is rotatably supported between the fixed frames; a turning plate is fixed on the main shaft; the main shaft penetrates through the turning plate and does not penetrate through the long central line of the turning plate.

When in use, the lower end of the fixing frame of the utility model is fixed on the position of the overhead ground wire close to the truss, the fixing frame keeps vertical, and the main shaft is horizontal to the ground wire; because the main shaft does not pass through the central line of the turning plate, the turning plate can not be kept horizontal in practice and is in a vertical state (as shown in figure 1), birds can not stand on the turning plate, and the harm of the birds standing on the overhead ground wire to the ground wire is effectively avoided.

The utility model provides an overhead earth wire do not have the current situation of anti-bird device, be a small, be convenient for installation, prevent that the bird is effectual overhead earth wire anti-bird device. And is different from the traditional barbed bird-preventing device, is harmless to birds and cannot injure the birds.

Detailed Description

An overhead ground wire bird-preventing device comprises a pair of fixing frames 1 for connecting with an overhead ground wire 4; a main shaft 2 is rotatably supported between the fixed frames 1; a turning plate 3 is fixed on the main shaft 2; the main shaft 2 penetrates through the turning plate 3 and does not penetrate through the long central line of the turning plate.

The fixing frame 1 is of a rod-shaped structure, and the lower end of the rod-shaped structure is used as a fixed end of the overhead ground wire 4; the upper end of mount 1 is equipped with the through-hole, and main shaft 2 passes the through-hole setting, and the through-hole outside is fixed to be equipped with the stopper.

The fixing frame 1 is of a rod-shaped structure, and the lower end of the rod-shaped structure is used as a fixed end of the overhead ground wire 4; the upper end of the fixed frame 1 is provided with a through hole, and a bearing is arranged in the through hole; the main shaft 2 is supported by bearings.

The lower end of the fixing frame 1 is fixed with an elastic clamp.

The lower end of the fixing frame 1 is of a structure with a downward opening, and a jacking screw is arranged on the opening. The two structures of the line number are selected according to requirements and are used for being fixedly connected with the overhead ground wire.

The main shaft is parallel to the long central line of the turning plate and does not penetrate through the long central line, so that the turning plate can be kept in a vertical state, and birds cannot stand and fly away.

The main shaft can directly penetrate through the through hole of the fixing frame, and a limiting block is fixed on the outer side of the fixing frame, otherwise, the main shaft falls off; the main shaft can rotate in the through hole; or the main shaft is fixedly connected with the bearing inner ring through the bearing arrangement fixed in the through hole, so that the rotation is convenient.

The lower part of the fixed end adopts a structure that an opening is matched with a jackscrew and is used for clamping and connecting with an overhead ground wire; or an elastic clamp is adopted to clamp the overhead ground wire, and the turnover plate is ensured not to be contacted with the overhead ground wire (as shown in figure 2).

Generally speaking, birds all like the position of standing near iron tower truss and with truss connection's ground wire, and the ground wire is more stable here, and in other positions of overhead earth wire, owing to keep away from the ground wire stiff end, the ground wire rocks great, and birds are generally not standing, consequently is installing in the position that is close to the truss the utility model discloses, just can satisfy overhead earth wire anti-bird's demand.
